IMPROVEMENT IN GULTIVATORS.

To all 'whom 'it may concern Beitknown that LTEADDEUs S. ScovrLLE, ofNew York, in the county of New York and State of New York, have inventeda new and Improved Cultivator; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the aecompanying drawings, making part of this specitication- Figurel being a plan of the machine; Fig. 2, a side elevation thereof Fig. 3,a rear elevation thereof.

Like letters designate corresponding parts in all the figures.

Two parallel side beams, A A, are provided, situated at a suitabledistance apart, and connected together by hinged bars B B, substantiallyas represented in Figs. l and 3. To the front end of said side beams arehinged thills C U, the cross-bar a, connecting said thlls, being jointedin the middle at b to correspond with the joints of the hinged bars B B,so as to allow the frame to adapt itself to unevenness of ground, andespecially to allow it to pass in the hollows or depressions between therows of corn, &c. The side beams are supported by spur-wheels D D D D,turning on journals c c ce, the front wheels being situated on theinside of the side beams, and the rear ones being situated on theoutside thereof. These spurwheels act both as supporting-wheels andculvators, and are constructed with hubs d d and spurs ff, the outerends of said spurs being bent or curved, as represented in Fig. 2, forthe purpose of stirring the soil more thoroughly. Teeth E E are securedto the side beams, either between the front and rear spurwheels or infront of the foremost spur-wheels; These teeth are convertible, so as tobe used on either side of the machine, thereby turning the soil outwardor inward, as ma;r be desired.

Any arrangement whereby the teeth are readily secured to or removed tromthe side beams may be used. In the drawings, the shanks of the teeth arerepresented as passing up through the side beams, and nuts g g screwedthereon. A seat, G, for the drivers use, is situated over the middle ofthe inachine, being supported by bent rods or springs 7L h, secured tothe side beams, the portions thereof on which the seatrests sliding inguides t' t', formed by securing a plate, 7c, to the under side of theseat, as represented in Figs. 2 and 3, or in any convenient manner, sothat the frame may adjustitself without beingimpeded by said seat.

By using the spur-wheels D D, serving both as supporting-wheels andcultivators, in connection with the convertible teeth E E, the soil ismore thoroughly pulverized and cultivated, while less power is requiredto draw the machine than the ordinary toothed cnltivator.

The whole machine, arranged as above specified, is very effectual, andadapts itself to all kinds of ground and soil in a superior manner.

What 1 claim as my invention, and desire to secure by Letters Patent,is-

The combination and arrangement of the side beams, A A, hinged together,the jointed bar a. connecting the thills, the spur-wheels D D D D,acting both as cultivators and supporters, the convertiblecultivating-teeth E E, and the sliding or self-adjusting seat Gr,substantially in the manner and for the purpose herein specified.

In witness that the above is a true specification of myimprovedcultivatorhereunto set my hand this 21st day of October, 1859.
